Hi all, I have a radio controlled clockwork boat I restored. It is old, about 80 years or so was made as a wooden boat 30 inches long and the motor is a specialised clockwork model boat motor. My first identification of it was from the excellent articles called Flotsam and Jetsome by John Parker in Model Boats magazine. The RC switches the motor on and off plus rudder.
I have been asked to send in an article to Model Boats magazine and I need to take out the clockwork mechanism and photograch it, which I will do.
I can endorse what Colin says that about halfway throuh the 7-8 minutes run time there is a shudder in the boat as the spring repositions itself. As far as I know nobody makes a clockwork motor, from what i have seen of gramophone motors they are very heavy and the power to weight ratio is not good.
I will have to save the rest for the magazine article. I had to withdraw an article on another subject as I had earlier put details on this forum and MB were not willing to take it as it was no longer exclusive, pity really but that's the way it is.
regards Roy
